CONNECTOR FOR ELECTRlCAL CONDUCTORS.

Patented Sept. 25, 1906.

Application filed May 23, 1905. Serial No. 261,785.

To all whom it may concern.-

Be it known that 1, PAUL F. WILLIAMs, a citizen of the United States, residing at Chicago, in the county-of Cook and State of Illino1s, have invented a certain new and useful Improvement in Connectors for Electrical Conductors, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to devices bywhich connection can be made with the ends of electrical vconductorsas, for instance, between two cables or between a cable and an overhead conductor. I

The principal object of the invention is to provide a simple, practical, and effective connector or joint of the kind described, and especially to dispense with the use of a solder wipe-j oint therein.

In-the accompanying drawings, Figure 1 is a view of a pole andan overhead wire and cableconnected together by a connector embodying my invention. Fig. 2 is a longitudinal section'through such a connector. Fig.

Fig. 4 is a section taken on line 4 4 in Fig. 2& Figs. 5 to 10, inclusive, are views of modified forms of construction. Figs. 11, 12, and 13 are views of two modified forms, each for connecting a lurality of cables.

Referring st to Figs. 2, 3, and 4, the device shown comprises a casing 1 and a cover or hood 2,fitted to the opentop of the casing 1, both made of insulating materialsu ch,

A'cable 3 is extended up through an aperture in the bottom .of the casing 1 and providedrwitha" terminal 4, which is conveniently in the form of a metallic spindle provided with a socket ada ted to receive the end of the conductor 5 o the cable, and-also provided with a larger gutwardly-facing socket 6. This terminal 4 is also provided with a laterally-projecting flange 7 to hold its'center within the casing 1, the side portions 8 8 of this flange 7 being cut away. 1 This terminal 4 is secured to the cable-conductor 5, preferably by soldering such conductor in the socket provided for it.

The space between the cable and its term nal 4 and the interior walls of the casing 1 is filled with 'minerallac or' other suitable insulating material 9, The hood 2 is provided with another terminal 10 conveniently in the 4'. The terminal 10 is secured to the end of a conductor 13, towhich the cable 3 is to bethe terminal 10 is provided with a socket adapted to receive the conductor 13, .and the latter is soldered therein. the top of-the hood 2 to receive the terminal 10 is also filled with insulating materialsuch, for example, as minerallac.

In: using the device the cable is first inserted through the lower end of the casing 1 and pushed up through the same, so that its conductor 5 projects from its open end, so as to be accessible, and then the terminal 4 is soldered to the conductor 5. The cable with its terminal is then pushed back into the easing and minerallac or other insulating material is poured into the cavity thereof until it fills or substantially fills the same, such ma- The aperture in and the split plug 12 pushed into the socket 6, thereby connecting the cable with the conductor or other cable. Thus it will be seen that the necessity of a wipe-joint in forming a terminal or connection for the cable is avoided, and at the same time the cable can be disconnected from its connection by merely removing the cover 2.

In using the device it may be used as shown in Fig. 1, in which is illustrated a pole or post .15, along the side of which extends a pipe 16, containing the cable 3, the upper end of the latter being provided with the terminal embodying my invention, which for convenience'is fastened by a band 17, attached to a block 18 on the pole 15. The pole is shown provided with a pair of insulators 1,9

19, to which is connected the overhead conductor 13, which is extended to and throu h the same and connected with the cable 3. n disconnecting the cable the cover 2, if removed, will hang, as shown in dotted lines in In Fi 3 is shown the device with' I cess to the interior of the device. The'other' modification is that the hood 2 and the casing 1 are threaded, so that the hood .is

- structed as to make itsattachment to a or otherarticle easy and convenient.

screwed upon the latter, and thereby held in position. I

This form of terminal consists of interengaging knife-blades- 23 23 on the lower terminal and blades 24 24 on the upperterminal.

l 11 Figs. 11 and 12 is-shown a device for the connection of a plurality of cables. This device comprises an insulating-base 28, made of porcelain onsimilar material, and a top or cover 29 of the same material, adapted to fit on'the base 28. "The base 28 and top 29 are nals, the constructionof which can be and is shown the same as the device of Figs. 2, 3, and 4. By this arrangement three cables of a three-wire system for example, can be connected and disconnected in any convenient 'In Fig.- 13 is shown a frame conveniently consisting of members 30 30, clamped together by bolts 31 31, embracing a p urality of terminal devices such as shown in Figs. 2,

3, and 4. By thisarrangement also a pluralit of cables of a two or three wire system can e accommodated. v

'It will be understood that changes and modifications can be made without departing from the s irit of the invention, and especially that w ile I have shown 'a cableconnectorherein the invention can be used for connecting other forms of elect1'ica l conductors. i

' What I claim is 1. A device of the class s ecified, comprising a pair of separable meIh ers composed'ofinsulating material, ,said members receiving and confining the ends of the conductors to be connected, means for connecting said conductors, and insulating material hermetically sealing the confined ends of the conducin said separable members. 7
